That is a picture of what Wikipedia sounded like when I screen-grabbed this from the Hatnote people. The idea is best described by them here:
Listen to the sound of Wikipedia’s recent changes feed. Bells indicate additions and string plucks indicate subtractions. Pitch changes according to the size of the edit; the larger the edit, the deeper the note. Green circles show edits from unregistered contributors, and purple circles mark edits performed by automated bots. You may see announcements for new users as they join the site, punctuated by a string swell.
It’s gorgeous and mystifyingly compelling. I found myself listening to it for almost half an hour while working. It’s surprisingly coherent, and while it probably punishes phone interfaces, I’d be interested in seeing this as a widget I could just turn on. Plus, then I can just listen to the internet directly, which, has to be an Xbox Live achievement or something.
